Amazon Elastic Kubernetes Service (EKS) is a service from Amazon that hosts a Kubernetes cluster in the AWS cloud. It's common for applications hosted in a Kubernetes cluster to require access to cloud resources outside of the cluster.

Amazon EKS supports using Open ID Connect (OIDC) to associate an AWS IAM role with a Kubernetes Service Account. This association allows you to securely grant access to cloud resources and manage these credentials.

In this hands-on laboratory, you will deploy an application that uses AWS cloud resources and observe it fail due to not having access. You will create a Service Account and configure it to be associated with an AWS IAM role. You will then configure the application to use the Service Account and observe it successfully accessing a cloud resource.

Upon completion of this intermediate-level lab, you will be able to:

• Inspect AWS IAM roles and Kubernetes Service Accounts
